[PATCH] gnulib-tool: fix imprecise comments

[Stefano Lattarini]

* gnulib-tool (func_emit_lib_Makefile_am): It's not just Automake
versions < 1.9b that creates an empty pkgdatadir at installation
time if pkgdata_DATA is specified to empty; modern automake versions
do this as well, and that's considered a feature, not a bug.  Adjust
a comment accordingly.
(func_emit_tests_Makefile_am): Likewise.
